To au" who/mit may concern! Be it known that l, CHRISTIAN F. Huss, acitizen of the "United States of America, and resident of Chicago,`Illinois, address care of A. NelsonMfg. Co.. 564-72 West Randolphstreet, Chicago, Illinois,) lhave invented a certainnew and usefulImprovementin Accelerators, of which the followin is aspecification. "1o

y `inventionrelates toV devices for accelerating the speedof anautomobile or similar engine.` Ordinarily this is done by meanso afootpedal--whicli is connected withl the throttle valve of the engine,,and which is employed in addition to the hand throttle which is usuallyassociated with the steering Wheel.

The purpose of this arrangement is .tol render it "celerator can beattached in place by bolts Y orzsimilar means involved in the construetion of the engine whereby the application ofthe accelerator to the'automobile'i's sini-l Elifed and rendered lless expensive than.eretofore; to `provide a novel construction and` arrangement` wherebythe vibration of "fthe car `While traveling over rough `roads 40'providece'rtain details and features of con struction tending toincrease' the general is a plan view, moregor less diagrammatic eciencyand desirability of an accelerator otliis particularcharacter. i

`To the foregoing and other useful ends my inventionconsistsin mattershereinafter described and claimed,but I do not limit myself to theexactconstruction disclosed.y

formed 'from sheet metal. The bracket plate A a5 has a pivotalconnection as with said plate a", whereby the latter turns about avertical axis. The arm a" integral ,with the plate a. and is connectedby AVa rod B with one arm oi the bell-cranl which latter is pivoted at c'to turn about a vertical axis. The throttle D ot the engine turns abouta vertical axis and is connected by a rod d with the arm 21, which`latter Ais mounted on the rod E which is associated with the column F ofthe steering wheel in the usual and well lnioivn manner. The said rod Eis connected with a suitable hand operated device onv the steering wheeland constitutes a controller for the throttle. said device being of suchcharacter, it will be understood., that this rod or controller E,

usf

gine at a certain ey reason of 'the i vspring device Z2 the rod ecanimoife endvvise :toward the lett Without aliectin'g the com trollerrod E, as the compression oit this spring Within the cylinder cl3.,which latter.'

is connected with the arm (il does not atleet the hand throttle. Thesaid rod el'is., lioW- ever, provided with a shoulder Z4 which prewillnotdisturb the accelerator, and will noix aiecti-,the speedof theautomobile; and to.-

dash Y of tlieautomobile and is disposed over the inclined foot board Zof the auto mobile body. The pivotal connections be'- tween the ears a2and ci 'permitftlie mein. ber A to rest onthe said foot board Z. the

foot portion a being depressed and held on the foot board by the tootVof tliedriver.

When it is desired to accelerate the engine,

^ the foot is moved sidewise against thellug being L-shaped in charactera1, thereby causing the arm atto swing about the vertical- Which causesthe rod. B to exert a pull through the bell-crank C and rod 01 on thethrottle arm D of the engine. This accelerates the engine to someextent, and lat such time the rod l movesto the left, but the yieldingof the spring d2 prevents this operation from disturbing the handthrottlc, in the manner previously described. As

soon 'as the foot portion-of the member A' is released by the foot, thespring cl2 then restores 'the throttle and the accelerator to theiroriginal positions,I thus the hand throttle can be adjusted to anydesired position, and this adjustment is not-.disturbed when theaccelerator is operated by thepfoot for the purpose of suddenlyincreasing the speed of the engine as is necessary, very often, whentraveling through crovvded4 streets.

In accordance With my invention, theA plate a5 is fastened to thevengine G by means of bolts g which are already on the enginethat is `tosay, these bolts are found on the engines of automobiles of certaintypes such for example as theFord automobile. This is also true of thebracket plate H upon which the bell-crank C is pi'voted, this plate issecured in place by a bolt which is foundon the engine. 'In this type ofautomobile, thebolts g are the :regular cylinder head bolts, and thebolty n is one of the bolts usually employed for holding the well knownWater inlet connection I in place on the side of the engine. Thisbracket l.I-I. is, therefore, of l.the shape I' 4shown in Fig. 3, havinganl opening iii/for the bolt mand an opening n2 for tlfpivot 40V boltnai of the said bell crank..,A curved notch n4 in one edge of thebracket H permits thesame to fit snugly at 'one side of the yportion aof the said Water inlet. It will also be observed that the rods c1 and ZeX- tend-across between the cylinders of the enweinefthe steeringWheelbeing at the left. yThe opening X is also found von a machine ofthis type. As' stated, therefore, the accelera'tor embodying theprinciples .of my in'- vention is adapted to be secured in place Withoutaltering -the construction of the i automobile, and Vby means of devicesfound thereon; What I claim as my invention 1s 1.
